Other and further objects, advantages and benefits of the invention will readily appear from a consideration of the followingsdescription and drawings forming a part here-1 of whereinz i i On the drawings:-' 1 I Figure 1 isa side elevation of an internal combustion engine showing the device at; tached thereto; i V

Near the bottom of a casing 13, a tube 26 is connected to a discharge opening 27. Oil passes thru strainer 28 into the tube 26 and thru it to the intake of an oil pump 29.

From the discharge of the oil pump 29 a tube 30 leads back into the crank case 11. By this means oil is kept in constant circulation from the crank case thru the oil purifier 13. Another pipe 31 may lead to other bearings requiring lubrication when the stop-cock 32 is open.

I may place a safety valve 33 in the upper part of the casing to vent the space 17 in event of too great exhaustion of the space 17.

The device may take other forms than that shown Without departing from the spirit of the invention and there Will necessarily be some modifications required to meet the individual peculiarities of different types of automobiles.

To meet these conditions is well within the knowledge of the artisan versed in the art.

I claim is my invention:

A device of the character described comprising a closed casing, a pipe extending thru the casing thru which to? pass hotgases to heat the contents of the casing, an oil inlet near the bottom of the casing for connection to the crank case of an engine, an opening at the upper end of the casing for a tube to connect it to the intake conduit of an engine, a discharge opening near the bottom of the casing -for connection of an oil circulating tube, an oil strainer in the casing overlying the latter opening, and a spring pressed valve connected to the upper end out the casing for opening inwardly of the casing.

In testimony whereof I have hereunto subscribed my name.

JOSEPH GRUBER.
